SSH

Secure Shell (SSH) provides a secure mechanism to log on to the vRouter and access the Command Line Interface (CLI).

SSH configuration

Configuring SSH is optional, but is recommended to provide secure remote access to the vRouter. In addition to the standard password authentication provided by SSH, shared public key authentication is also available.

The following table enables SSH for password authentication on the default port (port 22), as shown in the following figure. By default, only SSH version 2 is enabled.
